This option will unmount a currently mounted file system on a local disk or partition, create a NetRAID device, then re-mount the file system on the NetRAID device. Both the NetRAID device and the mounted file system are placed under LifeKeeper protection. You should select this option if you want to create a mirror on an existing file system and place it under LifeKeeper protection.
- Enter the following information when prompted:
|Existing Mount Point||This should be the mount point for the NetRAID device on the primary server. The local disk or partition should already be mounted at this location.|
- The following screen will display if you select a mount point that is not shared.
- Select Back to select a shared mount point. Provide the remaining information to finish configuring the resource.
|DataKeeper Resource Tag||Select or enter a unique DataKeeper Resource Tag name for the DataKeeper resource instance.|
|File System Resource Tag||Select or enter the File System Resource Tag name.|
Select the bitmap file entry from the pull down list.
Displayed in the list are all available shared file systems that can be used to hold the bitmap file. The bitmap file must be placed on a shared device that can switch between the local nodes in the cluster.
Important: The bitmap file should not reside on a btrfs filesystem (or any other SPS for Linux unsupported filesystem). Placing data replication bitmap files on a btrfs filesystem (or any other SPS for Linux unsupported filesystem) will result in an “invalid argument” error when LifeKeeper tries to configure the mirror. The default location for the bitmap file is under /opt/LifeKeeper. This default location should be changed if /opt/LifeKeeper resides on a btrfs file system.
Important: Do not select the shared disk area used for replication if displayed in the pull-down selection as the storage area for bitmaps. The shared file system allocated for replication cannot be used as the storage destination of bitmap files. You must use a shared file system location that has been allocated for just bitmap file.
- Click Next to create your DataKeeper resource on the primary server.
- LifeKeeper will verify that you have provided valid data to create your DataKeeper resource. If LifeKeeper detects a problem, an ERROR will appear in the information box. If the validation is successful, your resource will be created.
- An information box appears announcing that you have successfully created an existing replicated file system resource hierarchy. You must Extend the hierarchy to another server in your cluster to begin replication and to place it under LifeKeeper protection.
Click Next to extend the resource, or click Cancel if you wish to extend your resource at another time.
If you click Continue LifeKeeper will launch the Pre-extend Wizard. Refer to Step 2 under Extending Your Hierarchy for details on how to extend your resource hierarchy to another server.
